System Malfunction
Check Forward Collision Avoidance
Assist system
When the FCA is not workingproperly, the FCA warning light
( ) will illuminate and the warn-
ing message will appear for a few
seconds. After the message dis-
appears, the master warning light
( ) will illuminate. In this case,
have the vehicle inspected by an
authorized HYUNDAI dealer.
The FCA warning message may appear along with the illumination
of the ESC (Electronic Stability
Control) warning light.
The FCA is only a supplemen-
tal system for the driver’s con-
venience. The driver should
hold the responsibility to con-
trol the vehicle operation. Do
not solely depend on the FCA
system. Rather, maintain a
safe braking distance, and, if
necessary, depress the brake
pedal to reduce the driving
speed.
In certain instances and
under certain driving condi-
tions, the FCA system may
activate prematurely. This ini-
tial warning message appears
on the LCD display with a
warning chime.
Also, in certain instances the
front radar sensor or camera
recognition system may not
detect the vehicle or pedestri-
an ahead. The FCA system
may not activate and the
warning message will not be
displayed.
WARNING If there is a malfunction with
the FCA system, the Forward
Collision avoidance assist
system is not applied even
though the braking system is
operating normally.
If the vehicle in front stops
suddenly, you may have less
control of the brake system.
Therefore, always keep a safe
distance between your vehicle
and the vehicle in front of you.
The FCA system may activate
during braking and the vehi-
cle may stop suddenly shift-
ing loose objects toward the
passengers. Always keep
loose objects secured.
The FCA system may not acti-
vate if the driver applies the
brake pedal to avoid a colli-
sion.
The brake control may be
insufficient, possibly causing
a collision, if a vehicle in front
abruptly stops. Always pay
extreme caution.

Limitations of the System
The Forward Collision Avoidance
Assist (FCA) system is designed to
monitor the vehicle ahead or a
pedestrian on the roadway through
radar signals and camera recogni-
tion to warn the driver that a collision
is imminent, and if necessary, apply
emergency braking.
In certain situations, the radar sen-
sor or the camera may not be able to
detect the vehicle or pedestrian
ahead. In these cases, the FCA sys-
tem may not operate normally. The
driver must pay careful attention in
the following situations where the
FCA operation may be limited.
Detecting vehicles
The sensor may be limited when:
The radar sensor or camera isblocked with a foreign object or
debris
Inclement weather such as heavy rain or snow obscures the field of
view of the radar sensor or camera
There is interference by electro- magnetic waves
The FCA system does not
detect cross traffic vehicles
that are approaching.
The FCA system cannot
detect the driver approaching
the side view of a parked vehi-
cle (for example on a dead
end street).
In these cases, you must main-
tain a safe braking distance,
and if necessary, depress the
brake pedal to reduce the driv-
ing speed in order to maintain a
safe distance.
The FCA system may not acti-
vate according to the road
conditions, inclement weath-
er, driving conditions or traffic
conditions.
Occupants may get injured, if
the vehicle abruptly stops by
the activated FCA system. Pay
extreme caution.
The FCA system does not
detect all vehicles.
The FCA system operates
only to help detect vehicles or
pedestrians in front of the
vehicle.
The FCA system does not
operate when the vehicle is in
reverse.
The FCA system is not
designed to detect other
objects on the road such as
animals.
The FCA system does not
detect vehicles in the oppo-
site lane.

The vehicle is on unpaved oruneven rough surfaces, or road
with sudden gradient changes.
The vehicle drives through a con- struction area, on an unpaved
road, or above metal materials,
such as a railway
The vehicle in front is too small to be detected (for example a motor-
cycle or a bicycle, etc.)
The camera’s field of view is not well illuminated (either too dark or
too much reflection or too much
backlight that obscures the field of
view)
The camera does not recognize the entire vehicle in front.
The vehicle in front is an oversize vehicle or trailer that is too big to
be detected by the camera recog-
nition system (for example a trac-
tor trailer, etc.)
The vehicle in front does not have rear lights or the rear lights are not
turned ON or the rear lights are
located unusually.
The outside brightness changes suddenly, for example when enter-
ing or exiting a tunnel The vehicle drives inside a building,
such as a basement parking lot
The adverse road conditions cause excessive vehicle vibrations
while driving
You are on a roundabout and the vehicle in front circles
The camera lens is contaminated due to tinted, filmed or coated
windshield, damaged glass, or
stuck of foreign matter (sticker,
bug, etc.) on the glass
The camera is damaged.
The brightness outside is too low such as when the headlamps are
not on at night or the vehicle is
going through a tunnel.
Light coming from a street light or an oncoming vehicle is reflected
on a wet road surface such as a
puddle in the road
The field of view in front is obstruct- ed by sun glare
The shadow is on the road by a median strip, trees, etc.
The vehicle drives through a toll- gate. The windshield glass is fogged up; a
clear view of the road is obstructed
The radar/camera sensor recogni- tion is limited
The rear part of the vehicle in front is not normally visible (for exam-
ple, the vehicle is spinning or the
vehicle is overturned)
There is severe irregular reflection from the radar sensor
The sensor recognition changes suddenly when passing over a
speed bump

- Driving on a curve
The performance of the FCA system
may be limited when driving on a
curved road.
In certain instances on a curved
road, the FCA system may activate
prematurely.
Also, in certain instances the front
radar sensor or camera recognition
system may not detect the vehicle
traveling on a curved road.
In these cases, the driver must main-
tain a safe braking distance, and if
necessary, depress the brake pedal
to reduce your driving speed in order
to maintain a safe distance.The FCA system may recognize a
vehicle in the next lane when driving
on a curved road.
In this case, the system may unnec-
essarily alarm the driver and apply
the brake.
Always pay attention to road and
driving conditions, while driving. If
necessary, depress the brake pedal
to reduce your driving speed in order
to maintain a safe distance.
Also, when necessary depress the
accelerator pedal to prevent the sys-
tem from unnecessarily decelerating
your vehicle.
- Driving on a slope
The performance of the FCA decreas-
es while driving upward or downward
on a slope, not recognizing the vehi-
cle in front in the same lane. It may
unnecessarily produce the warning
message and the warning alarm, or it
may not produce the warning mes-
sage and the warning alarm at all.
When the FCA suddenly recognizes
the vehicle in front while passing
over a slope, you may experience
sharp deceleration.
Always keep your eyes forward while
driving upward or downward on a
slope, and, if necessary, depress the
brake pedal to reduce your driving
speed in order to maintain distance.

tem, for example, if the pedestrian
is leaning over or is not fully walk-
ing upright
The pedestrian is moving very quickly or appears abruptly in the
camera detection area
The pedestrian is wearing clothing that easily blends into the back-
ground, making it difficult to be
detected by the camera recogni-
tion system
The outside lighting is too bright (e.g. when driving in bright sun-
light or in sun glare) or too dark
(e.g. when driving on a dark rural
road at night)
It is difficult to detect and distin- guish the pedestrian from other
objects in the surroundings, for
example, when there is a group of
pedestrians or a large crowd

System Description
Blind-Spot Collision Warning(BCW)
The Blind-Spot Collision Warning
(BCW) system uses radar sensors in
the rear bumper to monitor and warn
the driver of an approaching vehicle
in the driver's blind spot area.
1) Blind-Spot Area
The blind spot detection range varies
relative to vehicle speed.
Note that if your vehicle is traveling
much faster than the vehicles around
you, the warning will not occur. 2) Closing at high speed
The Lane Change Assist feature will
alert you when a vehicle is approach-
ing in an adjacent lane at a high rate
of speed. If the driver activates the
turn signal when the system detects
an oncoming vehicle, the system
sounds an audible alert.
Blind-Spot Collision-Avoidance
Assist (BCA)
The Blind-Spot Collision-Avoidance
Assist (BCA) system helps detect the
front lane through the camera
installed on the upper front wind-
shield and helps the side/rear areas
through radar sensors.
The Blind-Spot Collision-Avoidance
Assist system may activate the
Electronic Stability Control (ESC) in
accordance with a colliding possibili-
ty with an approaching vehicle while
changing lanes. It is to help the col-
liding risk or mitigate the colliding
damage.

Driving your vehicle
Blind-Spot Collision-Avoidance Assist
(BCA) system is automatically deacti-
vated when:
- The vehicle drives a certain dis- tance away
- The vehicle direction is changed against the possible-colliding point
- The steering wheel is abruptly moved
- The brake pedal is depressed
- After a certain period of time
The driver should drive the vehicle in
the middle of the vehicle lanes to
keep the system in the ready status.
When the vehicle drives too close to
one side of the vehicle lanes, the
system may not properly operate.
In addition, the system may not prop-
erly control your vehicle in accor-
dance with driving situations. Thus,
always pay close attention to road
situations.
Detecting Sensor
(Camera and Radar)

The driver is responsible for
accurate steering.
Do not unnecessarily operate
the steering wheel, when the
Blind-Spot Collision-Avoidance
Assist System is in operation.
Always pay extreme caution
while driving. The Blind-Spot
Collision-Avoidance Assist
system may not operate or
unnecessarily operate in
accordance with your driving
situations.
The Blind-Spot Collision-
Avoidance Assist system is
not a substitute for safe driv-
ing practices, but a conven-
ience function only. It is the
responsibility of the driver to
always drive cautiously to
prevent unexpected and sud-
den situations from occur-
ring. Pay attention to the road
conditions at all times.

Front camera
The front camera is a sensor detect-
ing the lane. If the sensor is covered
with snow, rain or foreign substance,
the system may temporarily be can-
celed. The system is canceled due to
the degradation of the sensor's
detection performance. Always keep
the sensor clean.
* Refer to Lane Keeping Assist(LKA) System for cautions for the
front camera sensor.
Rear radar
The rear radars are the sensors
inside the rear bumper for detecting
the side and rear areas. Always keep
the rear bumper clean for proper
operation of the system.
The system may not work
properly when the bumper
has been damaged, or if the
rear bumper has been
replaced or repaired.
The sensing range differs
somewhat according to the
width of the road. When the
road is narrow, the system
may detect other vehicles in
the next lane.
The system may turn off due
to strong electromagnetic
waves.
Always keep the sensors
clean.
NEVER arbitrarily disassem-
ble the sensor component nor
apply any impact on the sen-
sor component.
Be careful not to apply unnec-
essary force on the radar sen-
sor or sensor cover. If the sen-
sor is forcibly moved out of
proper alignment, the system
may not operate correctly. In
this case, a warning message
may not be displayed. Have
the vehicle inspected by an
authorized HYUNDAI dealer.
Do not apply foreign objects
such as a bumper sticker or a
bumper guard near the radar
sensor or apply paint to the
sensor area. Doing so may
adversely affect the perform-
ance of the sensor.
NEVER install any acces-
sories or stickers on the front
windshield, nor tint the front
windshield.
Pay extreme caution to keep
the camera sensor out of
water.
NEVER locate any reflective
objects (i.e. white paper, mir-
ror) over the crash pad. Any
light reflection may cause a
malfunction of the system.
